Horizontal White Banding
White or Black Banding near the Edges
Cause Solution and Reference
The nozzles are clogging. Print the nozzle check patterns to check the nozzles for
clogging. If the nozzles are clogging, run a head cleaning by
pressing the Cleaning button for at least 3 seconds.
When Nozzle Check Mode is other than Anti-missing dot
mode, missing dots are permitted. If even one missing dot
cannot be permitted, change Nozzle Check Mode to Anti-
missing dot mode. (U "Auto Nozzle Check System" on page
104)
Cause Solution and Reference
The outside shutters on the
platen, which are not needed to
be opened for the paper, are open.
Air flow from the outside shutters adversely affect the printing
operation and may cause white banding on printouts.
Set the shutters on the platen according to the instructions on
the label attached to the printer. (U "Adjusting the Shutters"
on page 66)
